effect of fluid resuscitation on lactate in traumatic injury patients

Conditions: Fluid Resuscitation

Summary: the study aims to investigate the effect of 3% hypertonic saline resuscitation on lactate clearance in comparison to ringer's lactated solution and 0.9% normal saline in traumatic injury patients. also to provide insights into the optimal fluid resuscitation strategy for traumatic injury patients

traumatic injuries considered as important leading causes of morbidity and mortality worldwide; haemorrhagic shock is a common and critical complication. fluid resuscitation is a crucial step in managing traumatic injury patients, and the choice of resuscitation fluid can significantly impact patient outcomes. in the context of trauma, rapid and effective resuscitation is essential to prevent irreversible cellular dysfunction and multi-organ failure. lactate is a key indicator of tissue perfusion and oxygenation in trauma patients, with faster clearance rates associated with improved outcomes. there is growing interest in the use of hypertonic saline for resuscitation in traumatic injury patients, as it may lead to faster lactate clearance compared to traditional crystalloid solutions such as ringer's lactated solution and 0.9% normal saline. additionally, it has been suggested that hypertonic saline may improve microvascular blood flow and tissue oxygenation, which can aid in lactate clearance. ringer's lactated solution is commonly used for fluid resuscitation in trauma patients, providing volume expansion and buffering capacity. furthermore, 0.9% normal saline is widely utilized in clinical practice, but concerns regarding its potential to induce hyperchloremic acidosis have been raised. given the varied physiological effects of these resuscitative fluids, it is imperative to conduct a robust randomized controlled trial to elucidate their respective impacts on lactate clearance and overall outcomes in traumatic injury patients. such a comprehensive trial will facilitate evidence-based decision-making and potentially optimize resuscitation strategies in the acute care of trauma patients, ultimately improving survival and reducing the burden of trauma-related morbidity and mortality. to our knowledge there is few studies discussing the differences between the use of 3% hypertonic, ringer's lactated and 0.9% normal salines in urgent resuscitation of trauma patients.
